Did South Dakota angler find burial mounds on lake bottom?

Stark-Hump-of-Week-COLLAGEWhen South Dakota angler Paul Stark reviewed a custom fishing map he made with Insight Genesis, he discovered on the lake bottom what he believes could be Native American burial mounds.

«We have them by other lakes in this area of South Dakota,» Paul says.

Indeed, ten burial mounds in the Oakwood Lakes area in nearby Brookings, SD, are «typical of numerous such mounds in eastern South Dakota,» according to the text on a state historical marker there. Those mounds, dated about A.D. 300 to A.D. 1400, according to the historical marker, are probably the remnants of late Woodland or Middle Missouri Cultures.

«All of the mounds are strikingly similar about 3-6 feet high and about 100-150 feet in diameter,» the historical marker reads. «The so-called ‘Mound Builders’ made pottery, stone hammers and projectile points which may still be found in the area. … It is believed that the mounds were built by individuals who carried baskets of earth on their heads and then dumped the dirt to form mounds.”

Shown at one-foot contours at the bottom of a 424-acre lake near Madison, SD, the humps Stark discovered have such steep sides that they appear «almost 3D» on his Insight Genesis map, he says.  «Now that is detail on the humps! Man, I love mapping lakes and seeing stuff like this!»

Paul’s screenshot of these unique lake-bottom structures is this week’s Insight Genesis Hump Day «Hump of the Week.» Have you used Insight Genesis to locate bottom structure not shown previously on any other lake map?
